But Who We Are and How We Got Here only begins by exploring our relationship to ancient lineages of humans gone by.

Who We Are and How We Got Here is less than 300 pages of text, but it is packed with startling facts and novel revelations that overturn the conventional expectations of both science and common sense.

Who we are is humanity. And how we got here is interesting, astounding, but at the end of the day incidental. We are here, and have been for a very long time.
